What is the function of a "debugger"?

The function of a debugger is to identify and fix errors in software, making option B the correct choice. Debuggers are specialized tools designed to assist developers in analyzing the execution of a program. They allow users to step through the code line by line, inspect variables, and monitor the flow of execution. This process helps developers pinpoint the location and nature of bugs or errors in the code, which can range from syntax errors to logical errors. By using a debugger, programmers can modify their code and re-test it until they find a satisfactory solution.

The other options describe different tools or resources that serve distinct purposes in the programming environment. Translating source code to machine code is primarily handled by compilers, which process high-level code into a language that a computer's processor can understand. Database management software focuses on the organization, storage, and retrieval of data rather than debugging applications. Learning resources for programming languages involve tutorials, online courses, or documentation that help individuals gain knowledge about coding techniques but do not provide debugging capabilities. Debuggers play a crucial role specifically in the error resolution aspect of software development.
